TOROIDAL BOUNDARY LAYER GAS TURBINE
FIELD OF THE MENTION
[0001] Disclosed are embodiments of the invention which relate to, among
other things,
turbines and methods of generating power.
BACKGROUND
[0002] Prior art turbines and generators utilizing boundary layer effects
to generate
power, for example, those disclosed in U.S. Patent Nos. 1,061,206 to Tesla and
7,341,424 to
Dial, suffer from limited power output and efficiency.
[0003] Prior art turbines and generators relying on the teachings of Tesla
have failed to
take advantage of the simplicity of the Tesla design to generate maximized
power output and
there exists a need in the art for improved turbines and power generators.
SUMMARY OF THE INVENTION
[0004] By providing a combustion chamber extending about the circumference
of the
disc pack, a relatively simple construction permits considerable efficiency
and power output. The
configuration permits air and fuel to be mixed directly about the combustion
chamber to ensure
complete combustion of the fuel. This permits air and fuel to be mixed at a
plurality of locations
circumferentially about the chamber for increasing the power output by
permitting more fuel to
be consumed in an efficient manner and by imparting more rotational movement
to the products
of combustion.
[0005] By providing air and fuel tangentially into the combustion chamber,
the
combustion of the fuel can be contained about the outer periphery of the
combustion chamber by
the centrifugal forces imparted onto the fuel and air rotating about the
combustion chamber. The
centrifugal forces ensure that products of combustion are substantially fully
reacted before
overcoming the centrifugal force and outward pressure from the disc pack prior
to being
exhausted for optimal use of fuel.

[0006] By capturing air external to the turbine and allowing it to
descend substantially
rotationally through the thickness formed between the air inlet and combustion
chamber, air may
be provided about the outer periphery of the combustion chamber in a manner
that is
perpendicular to its origin direction, emulating the rotating flows in the
combustion chamber.

DETAILED DESCRIPTION
[0015] Figure 1 illustrates a turbine 100, which may comprise a
combustion housing 10,
nozzle ring 30 and a disc pack 50. Disc pack 50 holds a drive shaft 60, such
that the drive shaft
60 experiences the rotation of the disc pack 50. Disc pack 50 transfers power
output from within
turbine 100 to another device (for example, a generator or pump) via drive
shaft 60. A turbine
-2-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
axis 61 is located at the geometric center of the face of drive shaft 60. The
turbine axis
longitudinally runs along the shaft 60.
[0016] Combustion housing 10 carries within itself a combustion chamber 3
located
about the turbine axis 61 and through which combusted fluid travels to
generate power via shaft
60. The combustion housing 10 has an outside surface 1 and an inside surface
2. According to
an exemplary embodiment of the present invention, combustion housing 10 may be
made or
designed through known machining and/or molding processes with any material
that can
withstand high heat stresses and thermal shock, for example, but not limited
to, alumina,
graphite, silicon carbide (SiC), etc. Alternatively, this exemplary embodiment
of the present
invention may be made or designed through known machining and/or molding
processes with
stainless steel for smaller applications. Those skilled in the art will
recognize, however, that
material used to form combustion housing 10 of turbine 100 is not critical to
the present
invention and may include any material or composites thereof, which serve the
objectives
enumerated in the various embodiments according to the present invention.
[0017] According to the exemplary embodiment of the present invention
illustrated in
Figure 1, inside surface 2 may substantially enclose combustion chamber 3. In
another
exemplary embodiment of the present invention, inside surface 2 may create a
toroidal
combustion chamber 3. In yet another exemplary embodiment, inside surface 2
may create a
toroidal combustion chamber 3 whose cross section is substantially round
(e.g., circular or
elliptical or any other shape with rounded edges). In another exemplary
embodiment, inside
surface 2 may enclose nozzle ring 30, disc pack 50 and/or drive shaft 60.
According to another
exemplary embodiment of the present invention, inside surface 2 may come into
substantial
contact with the interior portions of turbine 100. Those skilled in the art
would also recognize
that those components that may be within combustion housing 10 may come into
substantial
contact with the inside surface 2 of combustion housing 10.
[0018] The combustion housing 10 contains openings 6 and 7 disposed
within the
combustion housing wall defined by surfaces 1 and 2. Fuel and air may flow
through openings 6
and 7 into channels 4 and 5 respectively. In one exemplary embodiment of the
present invention,
fuel channel 4 and air channel 5 may be placed in any organization located
about combustion
housing 10 providing fuel and air from within the combustion housing wall into
the combustion
-3-

WO 2010/051338 PCT/US2009/062479
chamber 3. According to an exemplary embodiment of the present invention
depicted in Figure
1, the fuel and air channels 4 and 5 may be located circumferentially about
the turbine axis 61.
In a further exemplary embodiment of the present invention in Figure 1, the
fuel and air channels
4 and 5 may alternate in their placement about the circumference of combustion
housing 10.
Those skilled in the art may recognize numerous other alternative
organizations of fuel and air
channels 4 and 5 about the combustion housing 10 and combustion chamber 3
depending on the
desired operation of turbine 100. In the exemplary embodiment of the present
invention
according to Figure 1, fuel and air channels 4 and 5 may provide their
respective fluids in flow
patterns which aid combustion of the mixture in combustion chamber 3.
Alternatively, the fuel
and air channels 4 and 5 may provide their respective fluids in flow patterns
which ultimately
will increase the power translated to drive shaft 60 from those fluids'
interaction with disc pack
50.
[0019] Further description of combustion housing 10 and combustion
chamber 3 will be
made with reference to Figure 2.
[0020] Referring back to Figure 1, in one exemplary embodiment of the
present
invention, the nozzle ring 30 is disposed between combustion chamber 3 and
disc pack 50.
Nozzle ring 30 is formed of a distal surface 31, a proximal surface 32 and a
plurality of
combustion fluid ("CF") nozzles 33. Each CF nozzle 33 is formed between a
distal space 40 and
a proximal space 41. Distal surface 31 substantially encloses the remaining
portions of
combustion chamber 3 not enclosed by inner surface 2. Those portions of
combustion chamber 3
not enclosed by either inner surface 2 or distal surface 31 may provide
combustion fluid through
any one of the plurality of CF nozzles 33 through their respective distal
spaces 40. In an
exemplary embodiment according to the present invention, the combustion fluid
from
combustion chamber 3 enters any one of the plurality of CF nozzles 33 at their
respective distal
spaces 40 and exits via their respective proximal spaces 41.
[0021] In an exemplary embodiment according to the present invention,
nozzle ring 30
may be integrated with combustion housing 10 to substantially form a surface
encompassing
combustion chamber 3. According to this embodiment, a surface encompassing
combustion
chamber 3 may comprise inner surface 2, distal surface 31, and the walls
defining CF nozzle 33.

WO 2010/051338 PCT/US2009/062479
According to this exemplary embodiment, passage of fluid from combustion
chamber 3 to disc
pack 50 may be achieved through any number of the plurality of CF nozzles 33.
[0022] In another embodiment according to the present invention, nozzle
ring 30 is a
distinct component of turbine 100, separate and apart from combustion housing
10. Those
skilled in the art will recognize that integration of nozzle ring 30 with
combustion housing 10
can affect the same combustion chamber 3 characterization described above.
Further, those
skilled in the art will also recognize that separation of nozzle ring 30 from
combustion housing
will not result in substantial deviation from the objectives of the various
embodiments of the
present invention enumerated herein.
[0023] According to an exemplary embodiment of the present invention,
nozzle ring 30
may be designed of any material that withstands high heat stress and thermal
shock, for example,
SiC, stainless steel, etc. The material selected according to this particular
embodiment of the
present invention makes the nozzle ring 30 especially suitable for obtaining
high temperatures
and allowing combustion fluid coming in contact therewith to further combust.
[0024] According to an exemplary embodiment of the present invention
illustrated in
Figure 1, disc pack 50 resides within nozzle ring 30. Disc pack 50 contains a
plurality of discs
52 of such diameter and thickness and between-disc spacing that when rotated
by and within a
fluid, a boundary layer effect allows further fluid to move through disc pack
50 to cause rotation
of disk pack 50. The spacing between plates typically is selected to be
directly proportional to
fluid viscosity to achieve the desired boundary layer effect. Each disc 52 may
be connected to a
shaft mount 58 by a plurality of spokes 54. Alternatively, the disc pack 50
may be attached to
the drive shaft 60 by a plurality of spokes 54. According to an exemplary
embodiment of the
present invention, rotation of disc pack 50 may rotate drive shaft 60 about
turbine axis 61
creating power. According to another exemplary embodiment of the present
invention,
combustion fluid flows through the disc pack 50 over any number of the
plurality of discs 52
thereby driving drive shaft 60 in the direction of the combustion fluid flow.
The drive shaft 60
may be integrally attached to disc pack 50 at shaft mount 58. In another
embodiment according
to the present invention, disc pack 50 may use shaft mount 58 to relate the
rotation caused by the
combustion fluid through its discs 52 to drive shaft 60.

WO 2010/051338 PCT/US2009/062479
[0025] According to the embodiment of the present invention illustrated
in Figures 1-3,
exhaust 70 (depicted in the exemplary embodiments of the present invention
illustrated by
figures 2 and 3), leaves the disc pack 50 in a direction along the turbine
axis longitudinally
through any one of the plurality of disc pack exits 56 formed from the
arrangement of the spokes
54 of disc pack 50. According to an embodiment of the present invention,
exhaust 70 exiting
turbine 100 at turbine exit 8 may be the product of a plurality of combustions
taking place
between the combustion fluid and the combustion chamber 3, nozzle ring 30 and
disc pack 50.
In another embodiment of the present invention, the exhaust 70 exiting the
turbine 100 may be a
product of the combustions occurring within combustion chamber 3 and any one
of nozzle ring
30 and disc pack 50. In yet another embodiment of the present invention,
exhaust 70 exiting
turbine 100 through turbine exit 8 is produced as a result of substantially
complete combustion of
combustion fluid within chamber 3.
[0026] In another exemplary embodiment, combustion fluid within
combustion chamber
3 may receive centrifugal forces through increased pressure created by the
rotation of disc pack
50. According to one operation of this embodiment, the centrifugal forces
generated by rotation
of the disc pack 50 creates increased pressure beneath nozzle ring 30. The
increased pressure
beneath nozzle ring 30 may act on the combustion fluid within combustion
chamber 3, allowing
longer combustion of the combustion fluid within chamber 3. According to
another operation of
this embodiment, rotation of the disc pack 50 causes the combustion fluid in
combustion
chamber 3 to move distally from the turbine axis 61 towards inner surface 2
and/or the walls
defining any number of the plurality of CF nozzles 33. This allows for further
combustion of the
combustion fluid within chamber 3 and/or within nozzle ring 30, achieving
substantially reacted
product within turbine 100. Following such reactions according to these
embodiments of the
present invention, the substantially reacted product exists from turbine 100
as exhaust 70.
[0027] With reference to the exemplary embodiments according to the
present invention
described above, the rotation of disc pack 50 may force combustion fluid into
contact with the
proximal surface 32 of nozzle ring 30 allowing for further combustion
reactions of the
combustion fluid located near and between edges of discs 52 and proximal
surface 32.
[0028] Figure 2 depicts an exemplary embodiment of the side view of
turbine 100
according to the present invention. Within combustion housing 10, combustion
chamber 3 is
-6-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
illustrated in two sections 3A and 3B. Within combustion chamber 3A is a
circled symbol "0"
while combustion chamber 3B contains a circled symbol "X". According to this
and further
illustrations of embodiments of the present invention, an encircled"."
symbolizes fluid flows
out of the page while an encircled "X" symbolizes fluid flows into the page.
Accordingly,
combustion chamber sections 3A and 3B depict fluid flow in a counter clockwise
direction
(viewing turbine 100 from the side where drive shaft 60 protrudes through
turbine 100) causing
the same counter clockwise rotation 66 at drive shaft 60.
[0029] In the exemplary embodiment of the present invention depicted in
Figure 2,
turbine 100 comprises combustion housing 10 enclosing nozzle ring 30, disc
pack 50 and drive
shaft 60 at combustion housing shaft aperture 9. Shaft aperture 9 may comprise
any type of
aperture enabling fluid rotation of shaft 60 within combustion housing 10
(e.g., ball bearings,
magnetic bearings, lubricated surfaces, etc.). Those skilled in the art will
recognize numerous
ways in which aperture 9 may be designed and configured to permit consistent
and uninhibited
rotation of shaft 60 during turbine 100 operation.
[0030] The outputs of the inner workings within combustion housing 10 may
exit turbine
100 via turbine exit 8. According to one embodiment of the present invention,
turbine exit 8
may be adapted to connect to other devices for treatment and expulsion of
exhaust gases 70 from
turbine 100. In another embodiment, turbine exit 8 may be configured for
controlled release of
exhaust gases 70 from turbine 100. In yet another embodiment, the shape of
turbine exit 8 may
influence the vacuum effect generated at the flow points of exhaust gas 70.
[0031] Figure 2 depicts an exemplary embodiment of the combustion fluid
mixing in
combustion chamber sections 3A and 3B according to the present invention.
Referring first to
combustion chamber section 3A, each of fuel and air channels 4 and 5,
respectively, enter
combustion chamber 3A via channel outlets 72 and 71, respectively. Channel
outlet 71/72 may
be any aperture in inner surface 2 of the combustion housing through which
fluid from the
respective channel may enter combustion chamber 3. According to this exemplary
embodiment
according to the present invention, dashed lines located in fuel channel 4 and
air channel 5
illustrate the fluid flow of the fluid in each channel. Each channel 4 and 5
contains an opening 6
and 7, respectively, within the wall formed between surfaces 1 and 2 of
chamber housing 10.
Opening 6 of fuel channel 4 may allow for entry of fuel injectors or any other
type of fuel
-7-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
providing apparatus/arrangement known to those skilled in the art. According
to the exemplary
embodiment of the present invention in Figure 2, opening 7 of air channel 5
may allow for entry
of air from outside the combustion housing 10 or outside any other type of
combustion providing
apparatus/arrangement known to those skilled in the art.
[0032] According to the embodiment of Figure 2, combustion housing 10 may
be
coupled to air plate 20. Air plate 20 may provide an aperture 22 for reception
and rotation of
drive shaft 60 within the coupled configuration of combustion housing 10, disc
pack 50 and air
plate 20. According to one embodiment of the present invention, aperture 22
functions in like
manner to aperture 9 of combustion housing 10. Alternatively, aperture 22 may
utilize separate
fluid external to air plate 20 to maintain consistent rotation of shaft 60
rotating therein.
[0033] Air plate 20 may receive air from a source external to turbine 100
through one or
more air inlets 21. Each air inlet 21 may channel received air into one or
more openings 7 of one
or more air channels 5 through air nozzle 25. In this particular embodiment of
the present
invention, air plate 20 provides the air which is dispensed into combustion
chamber 3 of
combustion housing 10. In an alternative embodiment of the present invention,
air plate 20 may
be integrally formed with combustion housing 10. In another embodiment
according to the
present invention, air nozzle 25 may be seamlessly coupled to air channel 5 to
create fluent air
flow from air inlet 21 through outlet 71.
[0034] Fluent air flow through air channel 5 allows for smoother air
flows with
diminished turbulence in the fluid as it enters combustion chamber 3. In an
exemplary
embodiment of the present invention, centrifugal supplies of input air 75
(illustrated in the
exemplary embodiment of the present invention in Figures 5B, 6 and 7B) about
the surface of
air plate 20 permits air inlet 21 to feed turbulent input air 75 into air
nozzle 25 whose geometry
works to reduce turbulence of the input air 75 to establish air flows out of
outlet 71 of air channel
that are substantially tangential to input surface 2. In another embodiment of
the present
invention, the turbulence of input air 75 may be greatly reduced by the
combined geometries of
any one of air inlet 21, air nozzle 25, opening 7 of air channel 5 or outlet
71. Further discussion
related to the turbulence reducing geometries of the aforementioned
embodiments of the present
invention will be had with reference to Figures 6 and 7A-B.

CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
[0035] According to the exemplary embodiment of the present invention
illustrated in
Figure 2, the flows of fuel and air from the openings 72 and 71 of their
respective fuel and air
channels 4 and 5 flow substantially tangential into combustion section 3A and
then mix into a
combustible fluid as they flow throughout the circumference of combustion
chamber 3 from
section 3A to 3B. The initial combustion of the combustible fluid in the
combustion chamber 3
may be accomplished by means of ignition or heating from within the combustion
housing 10.
Those skilled in the art will recognize numerous ways by which combustible
fluid may be
initially ignited within combustion chamber 3.
[0036] As per another operation of an exemplary embodiment of the present
invention,
combustion housing 10 may achieve high enough temperatures to combust all
combustible fluid
therein and produce substantially reacted product before the combustion fluid
exits the turbine
100. In such an operation, numerous continuous combustions of combustion fluid
take place in
combustion housing 10. Alternatively, combustion fluid experiences longer
amounts of time
exposed to combustion processes within combustion housing 10.
[0037] According to one embodiment of the present invention, the
combustion chamber
may use catalysts (e.g., surface coatings) to cause substantially complete
combustion reactions in
the combustion fluid. Alternatively, another embodiment may use the forces
exerted by the
operation of turbine 100 components to act as catalysts to cause substantially
reacted products
from the combustion fluid. According to these embodiments of the present
invention, at high
enough temperatures, portions of turbine 100 cease to combust combustion fluid
and instead
catalytically convert that combustion fluid into fully reacted product. In an
exemplary
embodiment, pressure in combustion chamber 3 during the combustion process
compresses the
combustion gases and contains the combustion flames about inner surface 2. The
pressure in
combustion chamber 3 may be achieved by the backpressure from the rotating
discs 52 which
behave like a centrifugal compressor. Alternatively, these pressures may be
achieved from the
centrifugal force of the spinning combustion gases in a vortex flow. As per
the operation of this
exemplary embodiment, back pressure and centrifugal forces act as catalysts to
ensure
substantially complete combustion of the fuel and the primary products of
combustion before
exiting through disc exits 56 and turbine exit 8 to ensure optimal efficiency
of combustion in a
simple construction which can be readily maintained.

WO 2010/051338 PCT/US2009/062479
[0038] According to one embodiment of the present invention, once an
initial volume of
combustible fluid is ignited, subsequent channeling of fuel and air into the
combustion chamber
3 will result in continuous combustion of the mixed fluid flows. In this
embodiment, the
continuous provision of fuel and air via fuel and air channels 4 and 5,
respectively, creates a
continuous combustion vortex throughout chamber 3. The vortex flow of
combustion fluid
throughout chamber 3 aids in the full and complete combustion of that fluid
according to this
embodiment of the present invention. In another embodiment, once an initial
volume of
combustible fluid is ignited, the rotation of the disc pack 50 will create
sufficient force to push
subsequent combustible fluid volumes into ignitable contact with combustion
fluid (e.g., the
previously ignited combustible fluid flow) thereby continuing combustion
throughout
combustion chamber 3. According to yet another embodiment, once initially
ignited, there is a
continuous combustion of injected fuel and air in the combustion chamber 3
which is induced
into a circumferential combustion flow direction about the turbine axis 61 by
the tangential
injection of fuel and air into the combustion chamber 3. The expanding gases
resulting from the
combustion are forced under pressure through CF nozzles 33 in the nozzle ring
30 to be similarly
directed in the circumferential flow direction about disc pack 50.
[0039] According to an embodiment of the present invention, combustion
fluid may be
forced into contact with inner surface 2 due to pressure generated by the
rotation of the discs 52
of disc pack 50. In one aspect of this embodiment of the present invention,
combustion fluid
may experience pressure from the centrifugal forces from disc pack 50 moving
it distally from
turbine axis 61. Centrifugal forces generated by the circumferential flow
contain the combustion
of the fuel adjacent inner surface 2 of the combustion chamber while the
products of combustion
spiral inwardly to flow between discs 52 and subsequently exit through turbine
exit 8.
Specifically with reference to combustion chamber section 3A, the pressure
from the disc pack
50 centrifugal forces may urge the combustion fluid along the distal portions
of the inner surface
2 of combustion chamber section 3A opposite nozzle ring surface 31. According
to this
embodiment of the present invention, maintaining combustion fluid in contact
with the distal
portions of the combustion chamber 3 may permit further combustion reactions
to take place
thereby allowing full and complete combustion of the combustion fluid in the
combustion
housing 3. By obtaining all the combustive output from the combustion fluid to
generate rotation
in the disc pack 50 (and therefore drive shaft 60), this embodiment of the
present invention
-10-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
utilizes the combined operation of the components of turbine 100 to fully
combust all entering
fuel and air. According to this embodiment of the present invention, the
pressure used on the
combustion fluid minimizes exhaust 70 containing incompletely combusted
products. According
to the aforementioned embodiments of the present invention, the time of
combustion of
combustion fluid in combustion chamber 3 is maximized by use of centrifugal
forces thereby
achieving an increased number of instances of combustion along any chamber
portion 3A to 3B.
[0040] Another exemplary embodiment of the present invention may include
an inner
surface 2 of combustion chamber 3 which has a highly emissive coating to focus
the radiant heat
generated during the combustion process into the center of the combustion
chamber 3. Higher
emissivity constants indicate a material's ability to reflect the radiation
caused by convective and
conductive heat streams. According to this exemplary embodiment of the present
invention,
highly emissive coatings, such as SiC or other such coating materials known to
those skilled in
the art, on inner surface 2 refocus radiant heat energies into the center of
the combustion
chamber 3 to provoke further combustion of the combustion fluid located
therein. An additional
advantage to having a highly emissive coating as it relates to this exemplary
embodiment of the
present invention is that it extends the life of the material comprising the
combustion chamber 3
and reduces surface temperatures experienced on the walls of the combustion
housing 10 defined
by surfaces 1 and 2. According to another embodiment of the present invention,
high emissivity
may also preserve other components of turbine 100 (e.g., nozzle ring 30, discs
52 of disc pack 50
when combustion chamber 3 is integrated with nozzle ring 30, etc.).
[0041] In yet another exemplary embodiment according to the present
invention of
Figure 2, the heat of inner surface 2, distal surface 31, proximal surface 32
or discs 52 may
further combust the combustion fluid in its travel through turbine 100. In
this embodiment of the
present invention, the heated surfaces of the components of turbine 100 may be
hot enough to
cause successive combustion of the combustion fluid thereby creating exhaust
70 without any
unused combustion products.
[0042] In another embodiment according to the present invention, a
toroidal shape of
combustion chamber 3 allows for the achievement of a high enough temperature
to instantly
combust any fuel in the chamber once the chamber has warmed up and exceeded
the critical
temperature to combust such fuel. A substantially round toroidal shape of
inner surface 2 may
-11-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
have an optical focal point in the center of chamber 3 to concentrate infrared
heat radiated from
the chamber surface to help further combust/react fuel. In accordance with
other embodiments
of the present invention, the substantially round toroid of combustion chamber
3 enables
combustion fluid therein to achieve high temperatures and remain within the
combustion
chamber 3 for an elongated period of time exposed to such high temperatures.
According to
these embodiments of the present invention, combustion chamber 3's shape
enables substantially
full and complete combustion of combustion fluid therein.
[0043] In the illustrated embodiment of Figure 2, eight discs 52 are
oriented parallel to
one another so as to be perpendicular to the turbine axis 61 of the turbine
shaft at evenly spaced
positions in the axial direction. Although eight discs 52 are depicted
according to the
embodiment of Figure 2, any plurality of discs 52 may be suitable for the
disclosed embodiments
of the present invention. The discs 52 may be secured together by a plurality
of fasteners
extending through cooperating apertures spaced circumferentially about a
periphery of the discs
52 and located within each of the spokes 54 of the spacers and the discs 52.
At the periphery of
the discs 52 where they are maintained in a spaced apart relationship,
suitable spacer washers are
mounted therebetween to receive the fasteners therethrough at each of the
fastener locations. All
of the disc exits 56 of discs 52 are aligned with one another for
communicating exhaust gases
therethrough (see Fig. 3.). In conjunction with the aforementioned embodiments
of the present
invention, discs 52 run at such high temperatures that their surfaces may
break down any
contaminant on their surface allowing them to remain clean. Additionally, as
mentioned with
relation to other embodiments of the present invention, the high temperatures
of discs 52 further
combust combustion fluid entering the disc pack 50 from CF nozzle 33.
[0044] Referring to Figure 3, the combustion of mature combustion fluid
80 may create
turbulent fluid flows. According to an embodiment of the present invention in
Figure 3,
turbulent combustion fluid 80 is received by distal opening 40 in nozzle ring
30. With specific
attention to the nozzle ring section turning out of the page (33A), travel of
combustion fluid 80
through CF nozzle 33A may redirect the combustion fluid to flow tangentially
over the adjacent
surfaces of disc pack 50 (similarly in the direction of fluid flow in
combustion chamber 3).
According to the embodiment of Figure 3, once combustion fluid exits opening
41 of CF nozzle
33A, it flows over the surfaces of discs 52 where it may be received within
discs 52 in streams
55. According to this embodiment, streams 55 may experience limited impedance
in exiting

turbine 100 due to a vacuum effect caused by the exiting flow of exhaust 70
through turbine exit
8. The vacuum effect created by flow of exhaust 70 through turbine exit 8 may
substantially
remove all pending exhaust 70 within disc exits 56 allowing for subsequent
exhaust streams 70
to occupy those spaces. According to the embodiments of the present invention,
the vacuum
effect of exhaust 70 enables more efficient operation of turbine 100.
[0045] According to one embodiment, CF nozzles 33A and 33B promote
tangential flow
of combustion fluid over a certain surface area of disc pack 50. By increasing
the surface area
receiving the combustion fluid there over, this embodiment of the present
invention achieves
higher power output. According to another embodiment, CF nozzles 33A and 33B
contain
proximal openings 41 which aid the tangential flow of combustion fluid over a
certain surface
area of disc pack 50. By controlling the flow of combustion fluid out of CF
nozzles 33A and
33B, proximal openings 41 may accelerate the fluid through nozzle ring 30
thereby introducing
more forceful combustion fluid over discs 52 of disc pack 50 and thereby
achieve higher power
output. In yet another embodiment of the present invention, a combined use of
CF nozzles 33A
and 33B and their respective distal and proximal openings, 40 and 41
respectively, may achieve
combustion fluid flows that achieve greater power output for turbine 100
(e.g., varying
geometries of each to create higher accelerations of combustion fluid, greater
tangential flows,
etc.) The flow of gases in the tangential direction by the orientation of the
CF nozzles 33 serves
to drive rotation of turbine 100 by the interaction of the expanding exhaust
gases through the
space between discs 52. The exhaust gases spiral towards the central openings
56 in the discs 52
to be subsequently exhausted through the turbine exit 8 in chamber housing 10.
[0046] Referring to Figure 4, the embodiments of the present invention
relating to
continuous combustion of combustion fluid during turbine 100 operation may be
incorporated
herein. According to an exemplary embodiment of the present invention, mature
combustion
fluid 80 has vortices at distal surface 31. However, in this embodiment,
catalytic combustions 82
may take place anywhere along nozzle ring 30 at surfaces 31, 32 or along the
surface of CF
nozzle 33 formed by distal and proximal openings 40 and 41, respectively. The
catalytic
combustions 82 of mature combustion fluid 80 may aid the full and complete
combustion of the
combustion fluid while creating further turbulence in the combustion fluid.
According to this
embodiment of the present invention, CF nozzle 33 promotes the tangential flow
84 of the
mature combustion fluid 80 out of proximal opening 41. Similar to previous
embodiments of the
-13-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
present invention, combustion fluid 84 (exiting proximal opening 41) may
contact surface area
86 of discs 52 through combustion fluid streams 55. Further combustion may
occur through
contact of combustion fluid streams 55 over surface area 86 according to the
aforementioned
embodiments of the present invention. According to an exemplary embodiment of
the present
invention, an increased disc 52 surface area 86 provides for greater torque
being produced via the
boundary layer effect caused by interaction of streams 55 with discs 52. In
another exemplary
embodiment, increased surface area 86 promotes further complete combustion
about a disc 52 in
disc pack 50 using streams 55.
[0047] In another illustrative embodiment of the present invention,
Figures 5A and 5B
depict the external air-receiving surface of air plate 20. Air inlets 21 exist
on the external air-
receiving surface of air plate 20. Air inlets 21 may be arranged in any manner
to receive air into
turbine 100 through air channel 5. According to an embodiment of the present
invention,
compressed air 75 is provided in a circumferential pattern onto the air plate
20 thereby making
placement of air inlets 21 preferable about that same circumference where such
incoming air 75
would be incident on air plate 20. In another embodiment of the present
invention, input air 75
may include vortices and eddies that create obstacles for reception of the
same within air inlets
21. According to this embodiment, air inlets 21 may be placed in any
arrangement on the
exterior surface of air plate 20 that optimizes reception of air 75 within
turbine 100.
[0048] Figure 6 is a side view of air plate 20 according an exemplary
embodiment of the
present invention. As previously described, turbulent air 75 external to
turbine 100 is incident on
air plate 20. Air plate 20 may receive streams of the incoming air 75 via one
or more air inlets
21. Arrows representing incoming air streams from incoming air 75 flow through
air nozzle 25
through opening 7 into combustion housing 10. Once within combustion housing
10, the air
streams flow through air channel 5 into combustion chamber 3 via air channel
outlet 71. As
previously discussed, air nozzle 25 and air channel 5 may be a single conduit
for air to flow from
air inlet 21 to channel outlet 71 through both the air plate 20 and combustion
housing 10.
According to an embodiment of the invention, air nozzle 25 may be shaped to
reduce swirls and
vortices in the incoming air stream 75 so that the air may exit the air nozzle
substantially
tangential to the combustion flow in combustion chamber 3. An air nozzle 25
according to this
embodiment may be a parabolic channel or declining helical channel.
Alternatively, the
interactions of air nozzle 25, opening 7 and air channel 5 may act to reduce
swirls and vortices in
-14-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
the incoming air stream 75. In this manner, momentum of the air flow exiting
opening 7 in the
circumferential flow direction may have been maintained in that
circumferential direction
through air plate 20 and into air channel 5 to increase the resultant
circumferential flow of the
combustion air entering the combustion chamber 3 from outlet 71.
[0049] In one embodiment, air inlet 21 includes a hemispherical groove
within air plate
20 which receives air 75 that flows into the groove and slowly descends into
air nozzle 25. The
combined conduit of air nozzle 25, opening 7 and air channel 5 gently bends to
reduce random
swirls of the incoming air stream while also imparting an intended vortex air
flow that may
follow that of the fuel and prior combustion fluids within combustion chamber
3. In this
embodiment, the incidence of flow losses caused by drastic changes in air
stream direction may
be avoided. In another embodiment of the present invention, air inlet 21
includes a
hemispherical groove within air plate 20 whose bottom-most surface descends
parabolically into
air plate 20 and convenes with air nozzle 25. In that embodiment, the incoming
air 75 may not
experience sharp changes in direction thereby avoiding flow losses into and
through combustion
housing 10. Those skilled in the art will recognize numerous other air inlet
shapes and forms
that may reduce flow losses into and through air nozzle 25. Alternatively,
those skilled in the art
will recognize numerous other air inlet shapes and forms that may reduce flow
losses into and
through combustion housing 10.
[0050] In another embodiment, opening 7 may be shaped or formed in such a
way to
reduce turbulence of exiting air flows into combustion chamber 3. Those
skilled in the art may
understand opening 7 may have any shape or form that may reduce shock flows of
air into
combustion chamber 3. In one exemplary embodiment, opening 7 may be a helical
ramp which
gradually introduces air flowing through air nozzle 25 into combustion chamber
3.
[0051] According to the embodiments of the present invention depicted in
Fig. 7A, there
is an exploded view of air plate 20 and combustion housing 10 concentric with
one another with
turbine axis 61 as their concentric center. The exemplary embodiment of Figure
7A depicts air
plate 20 and combustion housing 10 with air inlets 21A-D, grooves 97A-D, air
nozzles 25A-D
and air channel outlets 71A-D, although any number of the aforementioned
inlets, grooves,
nozzles and outlets may be possessed by other embodiments of the present
invention. According
to Figure 7A, distance 95 represents an elongated wall made by the exterior of
air plate 20 and
-15-
CA 02739808 2011-04-06
WO 2010/051338
PCT/US2009/062479
inner surface 2 of combustion housing 10. Those skilled in the art may
recognize that the
distance 95 is merely an aid for viewing the exploded view in Figure 7A and is
not meant to
suggest any restrictive distance between air plate 20 and combustion housing
10. Those skilled
in the art may understand that any distance 95 between air plate 20 and
combustion housing 10
that can permit the disclosed air nozzle 25A-D functionalities would be
appropriate according to
these embodiments of the present invention. Thus, dashed-line paths 25A-D over
wall distance
95 represent air stream passages within the air plate 20 ¨ combustion housing
10 wall.
[0052] In
one embodiment of the present invention, each groove 97A-D represents an
indent in air plate 20 which descends further towards combustion housing 10 as
input air 75
approaches respective air inlet 21A-D. According to one embodiment, grooves
97A-D may be
equal in diameter to air inlet 21A-D. Alternatively, grooves 97A-D may be any
diameter
permitting a geometry for receiving the incoming air 75. In another
embodiment, grooves 97A-
D may be partially exposed to incoming air 75 and partially submerged under
the exterior air-
receiving surface of air plate 20. According to that embodiment, air inlet 21A-
D may also be
submerged under the exterior air-receiving surface of air plate 20. According
to the various
embodiments of the present invention, any number of grooves 97 and air inlets
21 may be
utilized to efficiently and fluidly transfer random incoming air 75 into air
nozzles 25.
[0053] In
one embodiment of the present invention, air nozzles 25A-D revolve about
turbine axis 61 such that the exit of an air nozzle is substantially located
under the inlet of
another air nozzle. According to one embodiment of the present invention in
Figure 7A, air
nozzle 25A allows incoming air 75 from air inlet 21A to exit at 71A which is
located at
substantially the same radial position as air inlet 21B. In this exemplary
embodiment of the
present invention, helically descending air nozzle 25A greatly reduces
propensity of turbulent air
75 to exit at opening 71A into combustion chamber 3. Additionally, helically
descending air
nozzle 25A imparts onto air flowing therein a flow pattern substantially
emulative of that
experience within combustion chamber 3. According to previously described
embodiments of
air channels above, opening 71A may be shaped to further reduce propensity of
turbulent air 75
from exiting into combustion chamber 3. Referring to those embodiments,
opening 71A may be
shaped or formed to minimize shock flows of air existing at the juncture of
opening 71A and
combustion chamber 3. In those embodiments, opening 71A may be a gradual
helical ramp into
combustion chamber 3. Alternatively, opening 71A may have a parabolic ramp
into combustion
-16-
CA 02739808 2011-04-06
WO 2010/051338 PCT/US2009/062479
chamber 3. Those skilled in the art would recognize opening 71A may be shaped
or formed in
any manner that will provide minimized shock flows of air into combustion
chamber 3. Those
skilled in the art would further recognize opening 71A may be shaped or formed
in any manner
that will reduce turbulence of incoming air 75 into combustion chamber 3.
According to this
exemplary embodiment, the helically descending conduit of air nozzle 25A
simultaneously
reduces turbulence in the incoming air stream and imparts on the air stream a
vortex flow that
would be substantially tangential to the combustion flow within combustion
chamber 3 (referring
also to Fig. 6.). As per this embodiment of the present invention, each
helically descending air
nozzle 25A-D is constructed to coexist throughout the wall formed between the
exterior surface
of air plate 20 and inner surface 2 of combustion chamber 10. In another
embodiment according
to the invention, air nozzles 25A-D may form substantially curved,
substantially non-helical
conduits which permit for greater addition of conduits in the device without
impeding flow paths
of prior air nozzles 25. In another embodiment according to the present
invention, air nozzles
25A-D may be designed to fit substantially close to one another to
simultaneously achieve
desired air flows described above but avoid conduit interference.
[0054] Figure 7B is a further illustration of an exemplary embodiment
according to the
present invention. As described in Figure 7A, input air 75 enters air inlet
21A over groove 97A.
In one embodiment, groove 97A reduces turbulence of incoming air 75. In
another embodiment,
groove 97A aids in capturing random air streams on air plate 20. As depicted
in the embodiment
of Figure 7B, air flow 75 entering air inlet 21A flows through the wall of air
plate 20 into
combustion housing 10. Once within combustion housing 10, air nozzle 25A
channels the air
into air channel 5A to exit into combustion chamber 3 (not shown) at opening
71A. According
to this embodiment of the present invention, opening 71A is located in
substantially the same
location as the air inlet and groove 25B and 97B respectively. As per this
embodiment, air
nozzle 25A may be formed as any type of revolving conduit that would allow for
exiting of input
air in a direction substantially tangential to the combustion fluid flow path
within combustion
chamber 3. The combustion air and the fuel may then mixed directly in the
combustion chamber
about the full circumference of the turbine assembly as the air and fuel flow
in the
circumferential combustion flow direction.
[0055] An air plate 20 constructed according to the embodiments of the
present invention
may be made from numerous machining processes known to those skilled in the
art, such as, for
-17-
CA 02739808 2016-05-17
example, CNC machining. The air plate 20 may be formed of any material known
to those
skilled in the art which possesses temperature tolerances that can receive
high-temperature air,
for example, carbon fiber or stainless steel.
[0056] According to the embodiments of the present invention, the
components
comprising turbine 100 may be interchanged and exchanged according to
requirements of turbine
100. Interchangeability and exchange of components of turbine 100 are made
possible due to
their modularity. According to one embodiment, the components may be separated
at their
junctures (e.g., junction between air plate 20 and combustion housing 10, disc
pack 50 and
combustion housing 10, etc.) to effect replacement and/or coupling of the
components to
additional components according to the requirements of turbine 100 (e.g., use
of combustion
housing 10 and disc pack 50 with a first air plate 20 to generate 50 Watts and
removal of air plate
20 for a different component for use of combustion housing 10 and disc pack 50
to generate 500
Watts). Those skilled in the art would recognize numerous ways in which the
various
embodiments of the turbine 100 components enumerated herein can be coupled to
maintain the
disclosed functionalities and operations.
